Why We Love It
The Shimano 105 FC-R7100 crankset offers an optimized balance between lightweight and efficiency without sacrificing stiffness. The crank is formed with hollow aluminum technology and finished with a durable gloss black anodized. The resin ribs on the back of the chainrings are Shimano 105's unique structural design that achieves both through weight reduction and crisp shifting performance.
